RAIL JOINT AND FASTENING.

SPECIFICATION forming part of Letters Patent No. 717,357, dated December 30, 1902.

Application I'iled October 6, 1902.

T0 all whom it may concern: l

Be it known that I, THOMAS F. DAvIEs, a citizen of the United States of America, residing at Duquesne, in the county of Allegheny and State, of Pennsylvania, have inven ted certain new and useful Improvements in Rail Joints and Fastenings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rail-fastenings and rail-joints, and the invention has for its object mainly to provide improved means whereby the rails may be securely fastened to a metallic tie and also whereby the rails may be held without the aid of bolts passing through the webs of the rails adjacent to the meeting ends thereof.

To this end my invention, briefly described, resides in an improved form ot' chair which is made in two sections or members and is securely fastened to the metallic tie; the sections or members of this chair are constructed to receive the flanges of the rail-base and hold the rail or rails securely in position. The two sections or members of the chair are joined together by a bolt which passes through overlapping tongues of the sections or members and through the top or upper liange of the metallic tie, the rails resting upon the several bolts and securely holding the same in position.

All of the above construction will be hereinafter more specifically described and then particularly pointed out in the claims, and in describing the invention in detail reference will be had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference will be employed for designating like parts throughout the different views, in which- Figurel is a cross-sectional View of the railfastening and rail, showing a portion of the tie in longitudinal section. Fig. 2 is a longitudinal sectional view through a part of a rail, showing the fastening and a part 0f the tie in top plan view. Fig. 3 is a detail perspective view of one of the sections or members, and Fig. 4 is a like view of a modified form of the same which may be employed as a brace at curves in the track.

In practice I may employ myimproved chair base.

Serial No. 126,139. (No model.)

vided, respectively,with overlapping tongues 5 and 6, which are provided with registering apertures 7, the tongue 5 having a recess or countersink 8 in its upper face around the aperture 7 to receive the head of the securingbolt 9, which passes through the registering apertures 7 and through the top face of the metallic tie. The tongue 5 of the member 3 of the chair projects outwardly from the inner face of the chair a distance above the base of the member or section equal to the thickness of the tongue, while the lower face of the tongue 6 is iiush with the lower face of the chair member 4, so as to lit in the space beneath the tongue 5 and the latter rest upon top of the former. Each member or section isrconstructed with an enlargement 10, eX- tending the length thereof, which is provided with a longitudinal groove 11 to receive the flanges of the rail-base. Where the base of the rail 12 is constructed with the flanges having both the upper and lower faces thereof at an incline, as is seen in Fig. 1, thegroove 11 will also have its walls at an incline to accommodate and receive the anges of the rail- I prefer to employ a rail having the base thereof in the form shown in Fig. 1, being practically that of an inverted V, and it will be observed that the rail rests directly upon the heads ofthe bolts 9, securely holding the latter in position. The sections or members of the chair are securely fastened to the tie by means of bolts 14, passed through the tie and secured by nuts 15, as shown..

I may, if desired, construct the sections or members of the chair, as seen in Fig. 4, with the enlargement 10I of a size to t up against `the web of the rails, and this construction may be particularly desirable on curves in the track'and the like.

To place the chair in position, the sections or members thereof will be first joinedtogether by the bolt 9 and then slipped on the end of the rail and moved up into position over their respective ties, where they are securely fastened bythe bolts 14 and nuts 15. It will be observed that lateral movement or IOO spreading of the rails is absolutely prevented, as the sections or members of the chair grip the rail-base anges and prevent any danger or lateral movement or spreading of the rails. Where a rail is employed with a base straight on the bottom, the grooves in the chair members or sections will be constructed accordingly.

Having fully described my invention, what Iclaim as new, and desire to secu re by Letters Patent, is-

1. A chair and rail fastening comprising two chair sections or members provided on their inner` faces with overlapping` tongues having registering apertures, a bolt passing through said apertures to connect the sections together, each chair section or member having longitudinal grooves extending at an incline into the top of the section or member and adapted to receive the flange of the railbase, and means for fastening the chair seotions or members to a tie, substantially as described.

2. The combination with a rail having a substantially inverted-V-shaped base, of a chair and fastening comprising two chair sections or members and provided with overlapping tongues having a bolt-opening, a bolt in said opening and engaged by the baseof the rail, the said chair-sections having grooves on their inner faces extending at an incline into the sections to receive the inclined baseianges of the rail, and means for securing the chair-sections to a tie, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

THOMAS F. DAVIES.
